Red kidney beans ( Phaseolus vulgaris ), Alaskan peas ( Pisum sativa ), Himalayan barley ( Hordeum vulgare ), and Tetratakus rye ( Secale cereale ) seeds were cultured on various concentrations of DMSO for different periods of time. Seed germination and growth of roots and plumules were measured to determine the effects of DMSO. Toxicity of DMSO was more clearly indicated by growth than by germination data. Recovery from subjection to DMSO for definite periods of time was shown. From the observed adverse effects of DMSO several mechanisms were suggested for DMSO action. Uptake of calcium, magnesium, potassium, and phosphorus increased with treatment time and concentration of DMSO. Uptake on a wet weight basis was doubled or tripled at 7.5% DMSO. If DMSO is to be used as a synergist for fertilizers, insecticides, etc., concentrations of less than 0.1% must be used because of adverse effects of higher concentrations on plants.
